Native API and hardware access
RoboVM includes a Java to Objective-C bridge that makes it possible to call
into the native iOS CocoaTouch APIs. Objective-C objects can be used just like
any other Java object.

Code reuse
Easily share code between desktop, Android and iOS apps. The standard classes
(java.lang.*, java.util.*, etc) included in RoboVM are based on Android’s
runtime.

Open-source
The compile time tools are GPLv2 licensed. Runtime code is licensed under
business friendly licenses, mostly the Apache License v2.0.

Familiar tools
RoboVM comes with Eclipse and Maven integration. Use the tools you’re used to
from the Java world.
